" BY E dward Patented Dec. 2, 1941 UNITED STAT FICE 1 Claim.

This invention relates to mops in general, and particularly to means forsecuring the string or yarn to a head and to attach the head to ahandle.

More specifically, the invention relates to a mop which is particularlyadaptable for use by roofers for applying pitch to a roof.

The primary object of the present invention is the provision of new andimproved means for tying or securing the mop strands of yarn or stringto a head and detachably connecting the head to a handle.

Another important object of the invention is the provision of a mopwhich has a threaded member engaging a loop which surrounds the yarn sothat the yarn will be held tightly in position and the head can bequickly applied to or detached from the handle.

A still further object of the invention is to provide a mop which iscapable of withstanding hard usage and relatively high temperatures,which is provided with means for holding the yarn in position andpreventing the yarn or strings from shedding, andwhich is adaptable tobe replaced whether the mop is hot or cold.

Numerous other objects and advantages will be apparent throughout thefollowing specification.

The accompanying drawing illustrates a selected embodiment of theinvention, and the views therein are as follows:

Fig. 1 is a detail elevational view of the mop and embodying theinvention;

Fig. 2 is a detail sectional view taken longitudinally through theimproved mop;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 2; and

Fig. 4 is a detail sectional view on the line of Fig. 2.

The particular mop herein disclosed for the purpose of illustrating theinvention comprises a body 5 made up of a plurality of strands of yarnor string passing through a loop 6. The loop 6 is preferably made ofwire, which extends through an opening 7 formed in the head 8 of anattaching bolt 9. The free ends H3 and ID of the wire loop 6 are woundabout the body of the bolt 9, as indicated at H, Fig. 3. A nut l2threadedly engages the threaded end l3 of the bolt 9 so as to clamp theyarn tightly in the loop 6 between the head 8 of the bolt and the nutl2. A disk washer M is preferably arranged between the under side of thenut l2 and the coiled ends of the wire loop 6 to permit easy rotation ofthe nut and to cause the washer to act as an Opposed, 3

pitch and then spread over the area.

clamping surface with respect to the nut head 8.

The bolt 9 is made of a length suificient to permit the threaded end l3to extend a substantial distance beyond the top of the nut 12 so as tomake a removable connection between the mop head and a handle socket IS.

The handle socket I5 is preferably made of metal and may comprise ametal tube having an upwardly flared or hell shaped upper end IE todetachably receive a handle I1. Therefore, the socket l5, whichcomprises a handle portion, and the detachable handle I7, is referred toherein as a handle member. A nut or other member I8 is arranged in thelower end of the socket member I5 and is securely fastened thereto bywelding or otherwise, the attachment herein shown comprising pins I9passing through the walls of the socket member l5 and into the body ofthe nut 18. The nut I8 is immovably and nonrotatably secured inposition, and where the socket member is round, as herein shown, theperiphery of the nut It will be round also. However, the nut is securedin the socket member in any desirable manner so as to prevent removal orrotation thereof. The nut I8 is provided with an internal threaded boreor opening 20 to receive the projecting threaded end l3 of the bolt 9.The handle is applied to the mop head by merely turning the handle andits attached socket member to effect a tightening screw threadedengagement between the bolt end 13 and the nut I8.

In the roofing art, hot pitch is applied over the roof area by the useof a mop dipped into the hot The rough, severe usage given the mopcauses the mop to wear out in a relatively short space of time, andtherefore a new mop head must be applied, and it is desirable that thechange be made as quickly as possible. When the mop is hot and coveredwith hot pitch, a considerable problem has been presented to the workmanin applying a new mop head quickly. The present invention, however,overcomes the difiiculty and disadvantages inherent in conventionalmops, because a new head can be applied quickly and readily by merelyturning the handle to release the handle from the nut. Also, when themop is cold, the pitch will adhere and stick to the various parts of themop, making the change of the new mop head to the handle very difficultin the conventional mops. In the present invention, however, nodifiiculty is encountered in loosening the handle from the head.Moreover, the structure is such that the contraction and expansion ofthe metal parts will not afiiect the quick removability and applicationof heads to handles. Moreover, the parts are generally standard and canbe purchased in the open market and quickly applied and assembled.

The mop head itself comprises the bolt 9, the wire 6, the washer l4 andthe nut l2, and they are delivered as a unit. Therefore, when a mop isWorn out, it is an exceedingly easy operation to unscrew the socketmember and its cooperating handle from the end of the bolt 9 and apply anew mop head. The socket member I5 is relatively long and, being made ofmetal, will not wear out or deteriorate, even though it is constantlycoated with pitch, both hot and cold.

The parts are rugged and are adaptable to hard usage and are notaffected by the temperature.

The invention, therefore, provides a mop of relatively few and simpleparts, which can be quickly and readily assembled, and which willwithstand hard usage to which roofers mops are subjected.

Changes may be made in the .iorm, construc- .tion and arrangement .ofthe pants without .departing from the spirit of the invention orsacrificing any of its advantages, and the right is hereby reserved tomake all such changes as fairly fall within the scope of the followingclaim. The invention is hereby claimed as follows: A mop including a mophead comprising a bolt having a threaded stem and a head at one end ofthe stem, said head being formed with a diametral channel, a length ofwire having its mid portion mounted in said channel and opposite endportions extending oppositely from said head and bent to form arcuateloops, the extremities of said end portions being coiled about the stemof the bolt to hold the wire in place on the stem, a bunch of mopstrings held by and within said arcuate loops, a nut on the bolt forholding the coiled extremities of the wire in longitudinally adjustedposition on the stem,

and .a tubular handle-socket member having a threaded collar secured onone end thereof and adapted for threaded connection on said stemoutwardly of and in position to lock with said nut to secure the maphead on the handle-socket member.
